Topic: Problems serving beer!! Help needed! (Read 4876 times)

Hey everyone. I'm honestly baffled I can't figure this out on my own but here it goes. This is a nitro problem. I kegged my special bitter and hit it with 4psi just to give it around 1 volume of co2. After that I connected my beer gas(75% nitro, 25% co2) and hit it with 25psi. After a couple weeks I go to pour a pint and it comes blasting out. Waaaaay too fast. I have no guesses after playing around with it the last week. Any help would be great.

First, decide how many volumes of CO2 you want in your beer. It is currently at ~1.9 based on the pressure and temperature. That is totally fine and roughly where I put mine, but it's your call.

If you are ok with that, then 25 psi is fine. Now you need a line long enough to restrict that pressure. 7' of 5/16" is not enough restriction, that is only about 3 psi of restriction. Even if it is 3/16" and we go with the max reported of 3 psi / ft, that's only 21 psi. In my experience though, the actual restriction is under 2 psi / ft, which is why I recommend going with at least 15 ft of line.

Let me ask you this - you had 7 ft for some reason, at what pressure? If this working for you on a different beer, it can help you figure out what kind of restriction you were getting with your line.

So apparently beer gas is a different animal, so should I go get 15-20ft of tubing and see if that helps?

No, beer gas is not a different animal. The problem is that you are pushing the beer through a short line at high pressure. Your pressure is correct for what you are trying to do, so you need a longer line to balance it.
